Influence Of High Performance Façade On Heating/Cooling Load In Office Buildings In London And Hongkong

Wei Wang, Chanakya Arya

Abstract: Office buildings are responsible for a significant amount of carbon emissions. A possible strategy for reducing emissions from this source in both hot and cold climates might be to specify high performance facades. This paper reports on an investigation using Tas on the merits of using high performance facades on office buildings in London and Hong Kong both of which have a high density of office buildings but quite different climates. The results show that whereas U-value has a marginal/negative effect on energy usage at these locations the influence of gvalue is somewhat more positive. Moreover, by selecting facades which minimise energy demand when solar irradiations are low and maximising the use of, for example, solar energy and air/ground source heat pumps at other times could significantly reduce carbon emissions from office buildings.
